Caspase-3/7, 8 and 9 activities in H400 cells treated with IC₂₅, IC₅₀ and IC₇₅ concentrations of DAM and NDAM for 24 h. a Treatment with IC₂₅ concentration; b treatment with IC₅₀ concentration; c treatment with IC₇₅ concentration. Data are presented as mean ± SEM from three individual experiments (n = 3). Statistically significant differences between control and treated cells were set at *P < 0.05, **P < 0.01.
